View ProductSelected conventional seed options may be available with inoculant coatings suitable for use in qualifying organic production systems, subject to certifier approval and applicable requirements.
These products are conventional, non-organically produced seed and should not be confused with certified organic seed. Selected products may be available without prohibited chemical seed treatments and with an OMRI-Listed inoculant coating.
For compatible legume species, the inoculant contains crop-appropriate rhizobia selected to support nodulation and biological nitrogen fixation. Rhizobial inoculation applies to legumes; grasses, cereals, brassicas and other non-legume crops do not require rhizobia.
An OMRI-Listed coating does not make conventional seed certified organic.
